STOP-ENDICATOR FOR LQOMS.

Specification of Letters Patent.

Eatented April 1'7, 1906.

Application filed June 30, 1905. Serial No. 267,758.

To all whom, it may concern:

Be it known that I, JOHN A. OoLLrNs,a citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in StopIndicators for Looms, of which the following is a specification.

This invention hasreference to an improvement in looms, and moreparticularly to an improvement in automatic indicators for looms,whereby on the stopping of a loom a visual indication is given to theoperator that the loom is stopped. Indicators for this purpose asheretofore constructed were fragile in construction and liable to breakor get out of order in use; also, their position on the arch of the loomnecessitated a fragile connection,

such as a cord or wire, to the shipper for operating the indicator, andthis position on the top of the loom-arch gave a visual indication tothe entire weave-room, which in practice is objectionable, as it is onlynecessary to notify the weaver tending the particular loom that isstopped.

The object of my invention is to improve the construction of a visualindicator for looms, whereby the construction is such that the indicatormay be secured to the side frame adjacent the breast-beam of a loom,thereby giving a better visual indication to the operator withoutnotifying the entire weave-room that the loom is stopped.

My invention consists in the peculiar and novel construction of a visualstop-indicator for looms, said indicator being secured to the side frameadjacent the breast-beam and operatively connected to the shipper-leverof a loom, whereby on the stopping of the loom the shipper leveroperates the indicator to move an indicator-plate into a visual positionand on starting the loom to move the in dicator-plate into an invisibleposition, as will be more fully set forth hereinafter.

Figure 1 is a side view of the front portion of a loom provided with myimproved visual stop-indicator and showing the indicatorplate in thevisible position in dotted lines. Fig. 2 is a front view of Fig. 1,showing the indicator operatively connected with the shipper-lever(shown in full lines) and the shipp erlever shown in dotted lines in theposition it would assume to move the indicator-plate into its visibleposition on the stopping of the loom; and Fig. 3 is an enlarged backview of the indicator broken away from the 100m and showing theoperative mechanism of the indicator-plate in the invisible position infull lines and in the visible position in dotted ines.

In the drawings, a indicates the side frame; I), the breast-beam; c, theshipper-lever; d, the shipperdever spring of a loom, and e my improvedvisual stop indicator for looms. The indicator 6 consists of a fiathollow boxshaped frame 6, open at both ends and having the central slote in its back and the downwardly-extending arm 0 An indicator-plate ahaving the pin 6 in a position to extend outwardly through the slot 6 inthe frame, is constructed to have a sliding fit in the frame and painteda conspicuous color, such as red or white. A bell-crank lever e ispivotally secured to the end of the arm 6 and has the slot e in theupper arm for the pin 6 and the slot a in the lower arm, as shown inFig. 3. A bracket e is secured at one end to the frame 6 and at itsopposite end to the face of the side frame a adjacent the breastbeam 1)by screws or other means, and an arm e is secured at one end to theshipper-lever c in a position for the free end of the arm to enter theslot a in and engage with the bellcrank lever 0 as shown in Figs. 2 and3. By this construction the box-frame e is rigidly secured to the frameof the loom in a position for the arm a on the shipper-lever c to engagewith the bell-crank lever e", which, engaging with the indicator-plate athrough the pin 6 on the indicator-plate, operates to move theindicator-plate in or out of the boX- frame 6 In the operation of myimproved stop-indicator for looms the operator starts the loom by movingthe shipper-lever c inward into the position as shown in full lines inFig. 2. This raises the arm e on the shipper-lever and through thebell-crank lever e and pin 6 moves the indicator-plate 6* out of sightinto the box-frame e The mechanism of the indicator is now in its normalposition, as shown in full lines in Fig. 3. On the stopping of the loomby the breaking of a weftthread or other causes the shipper-lever c isthrown in the usual way into the position as shown in broken lines inFig. 2. presses the arm 6 on the shipper-lever and through thebell-crank lever e moves the indicator-plate 6 out of the boX- frame 6into its visible position, as shown in dotted lines in Figs. 1 and 3,thus giving automatically a visual indication to the opera- This deandpin e i tor that the loom is stopped. The position of the indicator on aloom is such that when the loom is stopped the indicator-plate extendsbeyond the line of the looms, where it can be easily seen by an operatortending several looms.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A visual stop-indicator for looms comprising afiat, hollow, box-shaped frame open at the ends, an indicator-platepainted a conspicuous color in the box-frame, means for rigidly securingthe box-frame to a loom, the shipper-lever and means for operativelyconnecting the indicator-plate to the shipper-lever of the loom, wherebyon the starting of the loom the indicator-plate is drawn into thebox-frame out of sight and on the stopping of the loom theindicator-plate is moved out of the box-frame into its visible position,as described.

2. A visual stop-indicator for looms comprising a flat, hollow,box-shaped frame open at the ends and havin a central slot in its backand a downward -extending arm, an indicator-plate painted a conspicuouscolor in the box-frame and having a pin in a position to extendoutwardly through the slot in the frame, a bell-crank lever pivotallysecured to the arm on the box-frame and operatively connected to the pinon the indicatorplate, means for rigidly securing the boX- frame to aloom, the shipper-lever and means for operatively connecting thebell-crank le- 'ver with the shipper-lever of the loom,wherestop-indicator 6 consisting of a flat, hollow,-

box-shaped frame e open at both ends and having the central slot 6 andthe down-.

wardly-extending arm e an indicator-plate e in the frame 6 painted aconspicuous color and having the pin (2 in a position to extendoutwardly through the slot 6 in the frame, a bell-crank lever epivotally secured to the end of the arm 6 and having the slot e in itsupper arm for the pin e and the slot a in its lower arm, a bracket asecured at one end to the side frame a of the loom and at its oppositeend to the box-frame e by screws or other means, and an arm 6 secured atone end to the shipper-lever c in a position for the free end of the armto enter the slot 6 in and engage with the bell-crank lever e, for thepurpose as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
